Aluminum powder paste ball mill as an important equipment in mineral production, the operation of the aluminum powder paste ball mill needs to be particularly careful, whether the starting method of the aluminum powder paste ball is correct, is the key to ensuring its normal operation, in order to ensure the equipment can be smooth Running production efficiency, reducing hazards, we should start the equipment in accordance with the correct operating method, the technical staff of Hengchang Machinery Technical Department will introduce the start of the aluminum powder grinding machine from the three aspects of the preparatory, specific startup step and startup precautions. I hope to bring help, standard operation to the majority of users, to a large extension of the service life of the aluminum powder paste ball mill.
First. Preparation before the aluminum powder paste ball is started
1, the aluminum powder paste ball mill should be carefully checked before the connection bolts are tightened, the gear, the coupling, and the mine or other The tightness of the bolt, check the gear and the gear;
2, the mill that has not been taken after the new installation or maintenance, it must be rotated 2-3 turn before starting, Check if the mill is collided with other machines;
3, check whether the amount of oil in the roller bearing is satisfied with the production needs and timely supplement, the mass and quantity of the slag pump lubricants meet the production needs, timely replacement Or replenish the lubricating oil;
4, check whether various protective devices such as oil-oil protection parking is complete, reliable
5, check whether the instrument and protection device are good, whether the air pressure of the pneumatic clutch meets the requirements;Second, the starting step of the aluminum powder paste ball mill
1, start It should be connected to the production section of the work in contact with the mill, whether the insulation of the ball grinding motor is good, whether the excitation control cabinet trial allows power to boot, start the transmission motor, automatic gear start in the control device The motor can be started by the start button; manually block the motor, press the start button, the motor starts to rotate, and press the run button when the motor speed reaches the rated speed.
3, the level of liquid level in the slag tank is the impact of the pump to make the pump, while allowing the air in the slurry to have enough time to precipitate; observe the production of the cyclone Status, the normal production of the cyclone flag is from the exclusive umbrella, the suitable umbrella angle is 20 ° ~ 30 °, which is greater than the angle, and its sand sand is low.And the fine grain level is high, the fractional efficiency is low, and the concentration of the sand is large, and the coarse grain level in the overflow is large, and the grading efficiency is also low.Adjusting the amount of mineral pool charges control the concentration of the cyclone in the range, so that the rotation fluor is working well.
Third, the aluminum powder paste ball mill startup precautions
1.Time is generally 15-20S If the start button mill starts to rotate to the specified time mill does not reach the rated speed, the startup should be stopped immediately, otherwise the cell-sensitive varistor will burn.After stopping the startup, check the mechanical and electrical appliances carefully to find out the reason that is not started.Secondary startup and the last time interval of the first startup is more than 15 min.If the temperature of the cell-sensitive resistor is relatively high, it can be forced by the fan.
2, the mill continuous start is not allowed to exceed two times, and the three startup must be performed after a comprehensive examination.
